New technique for generating electricity from mechanical vibrations

New technique for generating electricity from mechanical vibrations By Richard Moss November 12, 2014 Natural vibrations caused by two surfaces with different work functions repelling and attracting each other can be used to generate electricity (Image: VTT) Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to “harvest” the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes, and this energy could potentially be used to power wearables and other low-power electronics. A work function is a property of the surface of a material that is defined as the difference between the energy of an electron at rest and the minimum thermodynamic work (another form of energy) that is required to remove said electron from the material. It’s often applied in photoelectric devices and cathode-ray tubes, and is sometimes guarded against in electronic circuits involving different metals, but it had not before been used in vibration energy harvesting. The VTT scientists created a parallel-plate capacitor with copper and aluminum that was hooked up to an external circuit. The plates’ respective work functions provided the initial one volt charge as electrons fled from one surface to the other. Different el...



Nvidia quarterly revenue tops Wall Street expectations

(Reuters) – Nvidia (NVDA.O) on Thursday posted higher fiscal third-quarter revenue that was above Wall Street’s expectations, fueled by the company’s latest graphics chips for personal computers as well as processors for data centers and cars. Revenue in the fiscal third-quarter ended Oct. 26 was $1.225 billion, up 16 percent from the year-ago quarter, compared with analysts’ average estimate of $1.202 billion. For the current fourth quarter, Nvidia said it expects revenue of $1.20 billion, plus or minus 2 percent. Analysts on average expected fourth-quarter revenue of $1.198 billion, according to Thomson Reuters I/B/E/S. Third-quarter net income was $173 million, or 31 cents a share, compared to $119 million, or 20 cents a share, in the year-ago quarter. Non-GAAP earnings per share were 39 cents. After struggling to compete against larger chipmakers like Qualcomm (QCOM.O) in smartphones and tablets, Nvidia has increased its focus on using its Tegra chips to power entertainment and advanced navigation systems in cars made by companies including Volkswagen’s Audi, BMW and Tesla (TSLA.O). In the third quarter, revenue from Tegra chips for automobiles and mobile devices jumped 51 percent to $168 million. Nvidia’s much larger PC graphics chip business expanded 13 percent to $991 million. Shares of Nvidia rose 1.34 percent in extended trade, after closing up 0.45 percent at $20.22 on Nasdaq.

Chip News

  Chipmaker AMD hires Dell senior executive in server push SAN FRANCISCO Mon Oct 27, 2014 5:49pm EDT (Reuters) – Advanced Micro Devices Inc said it hired a former Dell Inc [DI.UL] senior executive to lead the chipmaker’s push into microservers and other new markets. Forrest Norrod will be senior vice president and general manager of AMD’s enterprise, embedded and semi-custom business group and report to Chief Executive Lisa Su, AMD said in a news release on Monday. Norrod, 49, was general manager of Dell’s server business and joins AMD as the company develops chips for new low-power servers that might challenge heavyweight Intel Corp in cutting-edge data centers. AMD has been expanding into new markets including low-power “microservers” and game consoles, but progress has been slower than demanded by Wall Street. Earlier this month, Su took over as CEO, replacing Rory Read. Norrod fills Su’s previous position, which she h ad held temporarily since July. Following Su’s appointment as CEO, AMD announced on Oct. 16 it was cutting 7 percent of its workforce to reduce costs. SOURCE   Microsoft Said to Work on Software for ARM-Based Servers Source Microsoft Corp. (MSFT) is working on a version of its software for server computers that run on chips based on ARM Holdings Plc (ARM)’s technology, people familiar with its plans said, a move that could help loosen Intel Corp. (INTC)’s grip on the market. The world’s largest s...

NZXT S340 Chassis Teaser

A few days ago, NZXT teased us with their latest release of the NZXT S340 Chassis. Our first impressions with its latest addition is WOW! Talk about “value” with a retail price of right around $69.99 USD. With most Press Release we only get a glimpse of what to expect, but this time around, it is bit different. To make a long story short, I had been looking for a replacement panel for my NZXT Phantom P630 that I had managed to damage. So I took to NZXT’s website to purchase the replacement panel. After short chat with customer service rep Lauren Kim regarding my matter, she was able to help me by warrantying my existing panel and offered a replacement for FREE, talk about outstanding customer service! Since I was local to the NZXT headquarters, I had offered to come pick up the panel to save on shipping cost. During my visit, I managed to catch Eric Henry, a NZXT Community Rep at the office since it was still during business hours. Eric was nice enough to give me a short tour and I was able to meet with the Mitch from PR and the NZXT Staff. Great people by the way! While I was here, we were able to get first hand look at the NZXT S340 Chassis up close and personal. While the one they had on display was still a prototype, it was nice to see first hand what to expect before we receive our review sample. Here are some pictures of the NZXT S340 during our visit (sorry about the quality, I only had my cell phone with me at the time since the visit really was u...

Be Quiet! Gives their case a name.

It finally has a name…. At this past Computex in Taipei, Be Quiet! surprised many of us by showing off a custom design case. Nice clean lines, angled top cover, smooth front surface, matte black paint job with a bright contrasting orange trim and out cropped feet, did wonders for creating a bit of buzz. The case with no name would be their introduction into the already crowded and competitive chassis market. This is a divergence from Be Quiet!’s bread and butter, performance fans and power supplies with whisper quiet operation. We should have been expecting Be Quiet to join in the fray as noise reduction among enthusiast reaches epic importance, what better way to start a silent system other then the body that will hold everything else. There has been some speculation on the naming of this mystery chassis based on Be Quiet!’s previous products such as the Shadow Rock, Dark Rock, Dark Power, Silent Wing and Shadow Wing, true to form, Be Quiet! drops the name right in the middle of their naming convention, “Silent Base 800″. Why Silent Base 800? I would guess that it is silent, past that I have no clue. Guess we will have to wait until October, the expected release date, to find out more. What we do know is that it will be available in Black/Black, Black/Silver and Black/Orange (Just in time for Halloween). Surprisingly there is no mention of a Black/Red affair to coordinate with the vast majority of boards sold today. I leave you to check out t...

Newegg Hybrid Center Launch Party with AORUS

Sometimes being located in Southern California can have its benefits, and we’re not talking about the weather here. California being one of the larger states in the US houses most of today’s PC hardware and software companies. One of these companies is Newegg, and if you haven’t heard of Newegg; we have to say… you need to stop hiding under that rock. Newegg is one of the largest electronics e-tailers in the nation today. If you have ever thought about building a PC or looking for some of today’s latest gadgets, the one place you have probably searched is Newegg.com. Newegg houses some of the largest range of products available today in stock in their inventory and its where most of us PC enthusiasts turn to for some of the geek shopping. Today, at spur of the moment I was notified by a good friend of mine from NZXT (thanks Eric!) that Newegg was hosting a launch party at their new hybrid center. Newegg’s “will call” is located in City of Industry and has housed a space for many local consumers to be able to pick up their online orders; this allowed some of us locals to pick up the items and save some shipping costs if the item isn’t shipped for free. However, the space here was previously pretty empty and houses some chairs and seating in the waiting area and a counter to pick up your packages. But that wasn’t good enough for Newegg and now they have opened the “Hybrid Center,” which has some of today’s latest ...

Antec Announces New Availability of HCP 1300 PSU

Antec just announced that it’s highest end PSU, the HCP 1300 Platinum, is being released to new markets. What makes this interesting is they released this unit in India first, but now it looks like it’s hitting the American and European markets and possibly others that were harder to find mentions of. While the question may still remain of why a California based company would release a unit in India first, what makes this PSU more interesting is some new features that might be telling of the future of motherboards. The first feature of interest is the OC Link Technology. This actually came out a bit ago and allows two PSUs to be connected simultaneously to reach the power demands of a super high end system. With 1300 watts of power, it seems hard to imagine needing more than one unit, however, dual GPU cards can easily max out power demands once 2 or 3 of them are set up in one system. This could mean that there is a future for more dual GPU GFX Cards in the development pipes for the system builder. The more realistic reason though, is that with bit coin miners buying up power intensive AMD cards and running them 24/7, they need PSUs to have more than enough headroom over the power requirements of their systems so there’s less chances of burn outs. The other interesting feature to note is the inclusion of a 28-pin motherboard connector. The idea behind this is to future proof the PSU, but with new tech being more power efficient, it’s hard to im...

ASUS Z87 WS Motherboard Review

Introduction In the world of custom PC Building, consumers and builders frequently ask what the best motherboards are for Gaming PC Builds. While these are always valid questions, some folks are looking to build a high end rendering or workstation PC. The Z87 series chipset has plenty of options from the budget friendly models to enthusiast gaming motherboards; however, workstation motherboards are not as readily available. That changes today. We are going to be looking at a motherboard from ASUS, one of the few manufacturers who created a Z87 chipset based WS (workstation) motherboard to meet this niche market. We have the ASUS Z87 WS on our test bench, and we are going to put this baby to through the ringer. As an interesting aside, one of the few features of this motherboard which immediately caught our attention is the available support of Quad SLI and Crossfire with 4 PCIe slots available. Not many Z87 motherboards offer this out of the box. There are also tons of other features that we typically don’t see with your “typical” Z87 chipset motherboard. Does this bode well for this unique new board? Read on to find out! Let’s get the review started by talking about the 8 Series chipset, but first here’s a quick word about Asus:   Origin of the Name “Asus” ASUS comes from the last four letters of Pegasus, the winged horse in Greek mythology that represents the inspiration of art and learning. ASUS embodies the strength, cre...

The System Snicker of the Day: Nokia Cheats on Microsoft

As a hardware enthusiast, news can have many effects on me. I can get excited, become sad, laugh out loud and other times mildly snicker. This time I mildly snickered as I read that Nokia was releasing new Android phones. It wasn’t too long ago that they decided to go all in with Microsoft and release only Windows Phones, but the excitement of the new relationship has all but worn off, and Nokia found a new partner in Android. [Editor's Note: For now at least. Android Nokia phones will likely be a short lived venture once Microsoft actually takes the reigns of Nokia later this year.] Today the Mobile World Congress 2014 began and this announcement is just one of many that has the mobile market ecstatic, while leaving system builders in a slight lull. Don’t get me wrong, phones can be exciting, but this isn’t the huge announcement I’ve been waiting for. While I really could stand to upgrade my old Samsung Galaxy S (yes, the original one), the opportunity I saw in this announcement was a chance to talk about what I would like to see from Windows in the future. Windows 8, while not quite the disaster that was Vista, is still a major disappointment. Microsoft tried to make one OS that could span the bridges from phones, to laptops, to professional environments, and what they ended with was an overall failure in everything except maybe tablets. So what should Microsoft do next? Well, this is just one man’s opinion, but no matter how inconceivable, ...

Smaller Technology Killing the Overclock…or is it?

Let’s face it. Smaller technology sometimes scares us overclockers! I see my behemoth tower that’s as tall as my desk from the floor, and I wonder if the day will come if that tower is much smaller. The truth is, that is a very real possibility, especially with much of this mobile and small form factor technology today. The plug to overclocking is being pulled so that the consumers are stuck with exactly what they got. But have no fear, Overclockers! G.Skill has come to our rescue by showing us that smaller tech doesn’t mean smaller tweaks. Today, G.Skill just announced that its Ripjaws SO-DIMM 2133 MHz DDR3 memory was overclocked to an astounding 2600 MHz! Even if those DIMMs where full size DDR3, that would be an impressive overclock, but this is laptop memory! If that wasn’t enough, this overclock was achieved in ASRock’s barebones system, the “M8.” We’re not talking about a wind tunnel here. We’re talking about a tiny flat box that’s barely thicker than a tablet! While I might be exaggerating the size a bit, the point is well made that even if form factors permanently get smaller, overclocking isn’t going anywhere. I don’t see my giant tower going anywhere either in all reality, but as long as manufacturers are willing to give us the option, we’ll be more than willing to find the best ways to get the most out of any hardware we get our hands on. If you still don’t believe me, just do a search for a liquid cooled raspberry pi! Written by Josh...
